AZ1117CH2-3.3TRG1 from Diodes Incorporated, in a SOT-223. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | INPUT | power_in | Input voltage pin; the absolute maximum VIN is 18V and the recommended maximum input voltage is 15V. |
| 2 | ADJ/GND | power_in | Adjust/ground pin; adjust pin current is 60µA typical and 120µA maximum on the adjustable version, and it serves as GND on the fixed-output versions. |
| 3 | OUTPUT | power_out | Regulated output pin with output voltage accuracy of ±1% (except the 1.2V version) and a typical current limit of 1.35A; a minimum 10µF output capacitor is required. |
